WEIGHING APPARATUS. a

SPECIFICATION forming part of Letters Patent No. 704,065, dated July 8, 1902.

Application filed October 29, 1901- Berisl No. 80,393.' (No mndelJ To all whom it may concern.-

Be it known that I, JOHN MANES, residing at San Francisco, county of San Francisco, and State of California, have invented certain new and useful Improvements in Weighing Apparatus; and I hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanyipg' drawings, forming a part of this specification.

This invention relates to apparatus for weighing, especially heavy-articles,wl1ile they are in transit and suspended on trolley-ways and without removal therefrom, being an improvement on an invention described in Lettors Patent of the United States No. (560,007, dated October 16, 1900, and Letters Patent No. 677,526, dated July 2, 1901, granted tome lei-improvements in weighing-machines, also Letters Patent of the Republic of France No. 305,625, dated the 22d day. of November, 1900, assigned and issued to the Suspension Beam Scale Company of Qan Francisco, California, U. S. A., and Letters Patent of the Kingdom of Belgium No. 153,327, dated the 15th day of December, 1900, 'also assigned and issued to the Suspension beam Scale Company aforesaid.

My invention consists in a main scale-beam. pivotallysupported overa trolley-way, a movable section of the latter being suspended to the scale-beam, so that'weights of any kind when passing over this suspended portion of the trolley-way will rest upd'n and be borne by the main scale-beam,communicating a predetermined portion of the weightto a second indicating scalebeam that bears but a portion of the stress, accordingly as the fulcra are arranged. My invention also consists in a means of permanently adjusting the main or weighing beam and in various constructive and operative features hereinafter more fully explained, and illustrated by drawings that form a portion of this specification.

lhe object of my invention is to supply improved devices to accomplish the purposes before named, and to this end I-construct apparatus as shown in the drawings.

Figure I is a plan view of the main scale- I beam and a section of the trolley-way beneath the same. Fig. 11 is a side elevation of my improved apparatus transverse to the trolleyway; Fig. Ill, a horizontal rear elevation ataright angle to Fig, II; Fig. IV, a bottom'view of the devices for connecting or holding the trolley-way in alinement. I

In moving heavy articles on trolley-ways,

especially when these latterare placed overhead, it is desirable to ascertain the weight of such articles whilein transitor without their'being removed or disconnected from the trolley-carriage. The devices for thispurpose are susceptible of modification in various ways affording more or less security from accident or derangement and at greater or less cost of construction, and my present invention relates t o these latter-named features. 0 Referring to' nigmeralsjof reference on the different figures of the drawings, his the main scale-beam; 2, the ceiling to which it is suspended; 3, a. trolley-way on which. moves a roller-carriage 4.1

5 is a free section of the trolley-way suspended to the main scale-beam l by the links 7; 8,41 weight of anykind to be moved and weighed, and 9 an auxiliary scale connected by a rod 10 to the main beam 1, for purposes hereinafter explained.

6 is a hollow extension of the main beam 1 to receive permanent weights, such as lead shot, to produce a balance or equilibrium of this beam, made integral therewith and closed by a screw 21 when adjustment is made.

The fulcra 12 of the beam '1 rest in the shackles 13, suspended to the ceiling 2 by the hooks 14. The knife-edges 15 of the beam 1 receive the links 7, that are rigidly attached to and support the movable'section 5 of the trolley-way; as before explained.

The vertical position of the movable section 5 of the trolley-way is adjusted vertically by means of a turn buckle 17 in the rod 10 and 'is guided laterally, vertically, and also longitudinally by means of the adjustable stems 18, that pass through lugs 19 on the footings of the links 7 and by screw-nuts, as shown in Figs. III and IV. The stems 18 slide vertically in the slotted guides 20, the ends of the former hearing or touching therein to maintain longitudinal adjustment of the section 5, thus performing adjustment of this latter-in two different planes without friction that will interfere with free movement in weighing.

The fixed ways 3 are suspended to the ceiling 2 by rods 22 or are supported in any other suitable manner.

The auxiliary or-compound scale!) is by preference provided with several beams 23,

having the usual sliding weights thereon and graduated in'multiples of the first or top beam in the usual manner, the bottom weight 24 being, commonly employed to adjust the equilibrium of the scale-beams 1 and their connectedparts.

The main beam I isintegrally formed pref erably' cast of suitable material,-wi'th dual members 25 to spread and give stability in the direction of the trolley-way 3.

The operation is as follows: When the parts are erected and connected, the weight 24 is setin the middle of its beam justment each way,

to permit and the screw 21 is removed,

and the-spherical chamber 6 is supplied with 1 lead or other suitable heavy material until the beam 1 and its-connections are in equilibrium. The chamber 6 is then closed, and any further adjustment re ired is made by the weight 24 on the auxiliary scale 9. A weight of any kind, as at 8 in Fig. II, susg pended on the rolling carriage 4, can be mov on the section 5 of the trolle'-way, so i;

weight will rest on the knife-edges 15 of the resin beam 1, and the weight in pounds can means for adj u'sting the balance of said beam at one extremity thereof, a compound auxilthe fulcra 13 and 15 dinally Icy-section relative iary scale-beam at the other extremity thereof, suitably connected thereto, a trolley-way, a vertically-movable trolley-section suspended from said knife-edgesof the main scalebeam, and adjustable means for guiding said movable trolle'ysection relatively to said trolley-way,- substantially as-specified.

2. In weighing apparatus, a main scalebeam, dual intermediate section, fulcra andknifeedges on said dual members, a trolley-way, a vertically-movable free section of said trolleyl-way suspended from the knife-edges of said main scale-beam, suspensory links having transverse stems 18 adjustable longituon said trolleysection, and slotted guides on the fixed portions of the trolley-way cooperating with said transverse stems to per integrally formed with a divided or mit free vertical movement thereof, substantially assp'ecified. 4

3. In weighing apparatus, a main scaleeam having fulcra andknife-edges, a trol ley-way beneath, avertically-n1ovab1e section of said trolley-way suspended from said knifeedges, a roller-carriage or trolley adapted to traverse upon. said trolley-way and its movable section, guides 20 on the fixed portions of said trolleyway, and longitudinally-adjnstable stemslS on said movable section, cooperating with said guides 20 to limit lateral and, longitudinal movement while permitting free vertical movement of'said trolto the fixed portions of the trolley-way, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN MANES.
